My Clymer manual is not specific as to how to undo the shift rod from my motor so that lower unit can be removed. I have done this before, had to remove a bolt on left side of motor (looking from rear) that is almost impossible to reach. I have been told that there is a much easier way. Can anyone tell me how? Also, using muffs, do I need to be concerned about how much water pressure is turned on to start and run the motor?
